Upon the other endl of the truck A is fixed any desired lifting` device, O, to which motion is given by the horse-power B. D is a crane, brace, or any suitable equivalent, through or over which passes thclifting-line E, to which is attached the Weight F to be lifted.

If desired, I vcan so provide to drop the weight F, that it shall act as a post-driver.
